The pioneering GP, who runs the feted Bromley-by-Bow Health Centre in east London, is a man with many hats. The current chair of NHS Tower Hamlets CCG, he is a member of both the BMA and GMC Councils and the former deputy chair of the BMA.

The dramatic intervention, made in a health letter to the Prime Minister, was read out by opposition leader Ed Miliband amid angry exchanges in the House of Commons in February.
